Waste Water Flow Restrictor for Reverse Osmosis Systems, choice 400ML, 450ML, 500ML, 550ML. or 650ML

Waste Water Flow Restrictor for Reverse Osmosis Systems, choice 400ML, 450ML, 500ML, 550ML. or 650ML

Purpose: build pressure inside RO membrane housing (Countertop or Undersink RO systems).

Restrictor size needs to be correlated with GPD Membrane rating:

50 GPD RO Membrane – 400ML or 450ML

75 GPD RO Membrane – 450ML

100 GPD RO Membrane – 450ML. 500ML or 550ML

150 GPD RO Membrane – 550ML or 650ML

200 GPD RO Membrane – 650ML or higher
